Add Health Study

What Is It?

Group of high school students hanging outside during the school day.

The National Longitudinal Study of Adolescent Health (also known as Add Health, the Add Health Study, and the Add Health Survey) is a nationally representative study originally designed to examine how social contexts (such as families, friends, peers, schools, neighborhoods, and communities) influence teens' health and risk behaviors. The study is now examining how health changes over the course of early adulthood.
